By thv consti'uviion hvxvtofoi'e tlvsoxihed itV will im soun that when the locking ping is rotated by means ofthe key, the pinion `will cause simultaneous but reverse rotation of the cani arm through the pinion 10. "rum an inspection of Fig. 1, it will be seen that when a lock of this construction is mounted below the latch holt the pivot of ihr cam arm uill be located on that side of the @vlinder adjacent. the holt and consequently said arm will stand in a posltlon to operate the same upon rotatlon of the locli- UE plug. lt will also he observed that in thi position of the lock the tulnblers will extend alove the locking plug and hence wli he moved to operative position with re- A Slm-t to the key h v gravitj,Y as Well as .the artlon of the springs 5, so that notwith- Slauding defective action of an)y of thet Springs the tumbler-s will always drop by gravity to proper operative position.

While l have herein described a preferred rlnlmdinient of my construction, it is to he lllulerstood that. the @anniV may be varied in detail and relative arrangement of' parts t'nin the .wope of the appended claims.

What l claim is:

l` ln a cvlinder lock for bolt mechanisms, u ryii ndena key opcratable plug eci-.entrieal ly mounted in the lower portion thereof, tum ler mechanism for locking Said plug, said tlnnlwler mechanism being arranged in thev Cylinder above the plug, a holt controlling cnnwarm rotatably mounted at the inner end of the cylinder above the inner end of lw plug, and means of operative connection rtneen said plug and said cam-arm whereby rotation of the former will cause the rotaiion of the latter.

In a cylinder lock for holt mechanisn'ls, a cylinder, a key operatable plug,r ecc-entrically mounted in the lower portion thereof, tumbler mechanism for locking raid plug, said tumbler mechanism being arranged in the ovinder above the plugga holt controlling earn-arm rotatably mounted at the inner end of the cylinder above the inneil end of the` plaag, and means of operative connection hetween said pluto` and :said cam-arm whereby rotation or' the former will cause the rotation lof the latter, the faid connection menne cov;mrisinf; tivo inttomcshine geal respectively mounted on and rotatable with Said plug and cam arm. cylinder lock, compriaing a lock cylind a locking plug ccccntrically mounted lower portion thereof, tumbler nicchaniszn -overslamling Said plug, a pinion mounted upon the rear end of tid plug, a plaie detachallly mounted on said -yiinder allow said plug` a stud rotatably mounted in i plate, a cam arm and pinion carried by stud, `aid pinion lne hinf with ille lint lnernioncd pinion whereby Said loca may be natively mounted l'wlmv the latch holt the locking tumbler,` o\`vr ft'andiug said ng plug.
